“…Porosity was decreased while the uniformity was increased by increasing the temperature from 500 • C to 550 • C due to an increase in sintered density. Compared with other (Mahesh Paidpilli [35], V. Jaya Prasad [36], Z.Sadeghian [20]) Al-TiB 2 composite microstructures, TiB 2 particles were not clearly visible in the current work microstructures.…”

In this study, Al-TiB2 compacts fabricated by spark plasma sintering methods at different temperatures were characterized for densification, microstructural development, and mechanical properties. Sintering parameters used were temperatures of 500 °C and 550 °C under the pressure of 30 MPa. A very dense microstructure with uniform phase distribution and porosity was produced in the sample sintered at 550 °C with 2.5 wt% TiB2. The same sample exhibited excellent hardness value, and a high-tensile strength attributed to full metallurgical bonding, presence of sub-micron sized grains, and their uniform distribution. These results show that the TiB2 addition enhanced the composite’s hardness, sintered density, and tensile strength. In all the sintered samples, the fractographs revealed a mixed-mode fracture (ductile and brittle).

“…Reinforcement particle size plays a vital role in developing properties of composite, generally when particulates are microscale to nanoscale sizes [19]. Prasad et al [20] investigated the mechanical and wear behaviour of SiC/TiB2 particle reinforced Al6061 matrix composite fabricated by stir casting. it's noticed that TiB2 reinforced composite acquire more hardness and wear resistance as compared to SiC reinforced composite.…”

Application of SiC particulate reinforcement impact greatly for making aluminium matrix composite because of its superb heat conductivity, oxidation stability and highly resistance to mechanical erosion. Present work based on dry sliding wear analysis of Al7075/6wt.%SiC composite fabricated by liquid state stir casting method. To acquire a productive wear rate, three major process parameters viz. load, sliding speed and covering sliding distance were compared four different levels. ANOVA analysis showed that the probability rate of load is less than 0.05 that revealed their significant factor. From the study, the highest GRG and GFG values are found 0.914 and 0.854 respectively for the optimal operating parameters of 10 Newton load, 2 metre/second sliding speed and 500 metre sliding distance. Finally, it is revealed that the grey-fuzzy technique effectively authenticate the decision making of wear performance characteristics rather than a plain grey relational grade.

“…The uniform distribution of matrix grain sizes and the segregation of SiC particles along matrix grain boundaries were shown. Prasad et al [ 6 ] examined the influence of the TiB 2 and SiC adding on the microstructure and the mechanical and tribological properties of Al6061 MMC. The uniform distribution of TiB 2 and SiC particles and the intermetallic Mg 2 Si phases in an aluminium matrix were established.…”

On Investigating the Microstructural, Mechanical, and Tribological Properties of Hybrid FeGr1/SiC/Gr Metal Matrix Composites

In recent years, studies of different properties of hybrid metal matrix composites, as well as very detailed issues, have been published. In this article, ready-made iron, graphite, and silicon carbide powders were used to produce the base material and composites. An analysis of some microstructural and mechanical properties, as well as the tribological behavior of metal matrix composites (MMCs), based on FeGr1 sintered material with the single and hybrid addition of a silicon carbide and graphite was undertaken. During the study, the flexural and compressive strength of MMCs were analyzed and changes of the momentary coefficient of friction, the temperature of friction, as well as wear rates of the MMCs tested were monitored. Based on the results, it was revealed that wear rates decreased 12-fold in comparison to the base material when SiC or SiC + Gr were added. Further research into MMCs with ceramic particle additives is proposed.
